Monitor does not get any signal after upgrading motherboard & CPU

I ordered an EP-8KMM3I-X motherboard and an AMD Sempron 2400+ CPU from
newegg.com a couple of weeks ago, after I installed them in my computer
case and connected every peripheral devices, I turned on the power, but
the monitor does not get any signal.

You can view the motherboard he

However, the fan of the cooler works great, also, the HDD indicator is
on, but just the monitor does not get any signal. The 512MB DDR RAM is
good, too, because I tested it on another desktop and it works great.

The motherboard and the CPU (the entire system actually) worked great
before I tested them outside the case.

Is it possible that the motherboard has been damaged?

Could any of you please help me trouble shoot this? Thanks.

Permanently?

You tested them outside of the case?

You should test with the bare minimum components.

Yes, I tested them outside of the case.

Bare minimum components, what else can I take off? HDD? RAM?

Are you sure that the monitor is plugged into the correct video out and that
is the video out which is selected in the BIOS? i.e., that you haven't
selected "on-board" video and then are plugged into an AGP card?

Well, the onboard video support is the only video out I have. I am not
using any PCI or AGP video card. As a matter of fact, those slots are
not used at all at this point of time.

What else might it be? Thanks.

Yes, only one stick of RAM. Everything except the bare minimum.
You should not include any peripherals.

You do not need a hard disk drive to test.

The only thing you should use when things go wrong is video and
keyboard. Remove everything except one stick of RAM. Be sure to
use a CPU heatsink and fan.

O, I just put the motherboard on top of the case and connect the powers
then powered it on.

I have only one 512MB DDR RAM, which has been tested and it works
great. I'll try the minimum. I do have a CPU cooler.

Now, is it possible that the motherboard has gone bad?

on a side note: this has been done with the old harddrive and OS
installation?
have you tried clearing the cmos yet?
your PSU is up to par with the new board?

Yes, even likely, if the bottom of your mainboard was touching
metal.

If not, anything is possible. Again, you test by using minimum
components.

I ran into something similar recently. Here's what I was told to do on the
group.

1. Take the mobo out of the chassis.
2. Take out everything except the CPU (even the memory) and the ATX 12V
connector.
3. Turn the PC on. You can do that by shorting the two connectors for the
power switch.
4. If you hear beeps, the board and CPU are fine.
5. Now add RAM. Repeat 3, 4.
6. Now add video. Repeat 3, 4.
7. Now, slowly add other things.

At some point, you'll find your problem.

Good luck.
